1 Claim.

Certified and other special grades of milk that sell at a premium are ordinarily bottled in the country and shipped or trucked to town in some type of box or container that can be iced. As such 5 milk is often used for babies and invalids, it is necessary to keep it properly refrigerated until the time it is used. Heretofore, boxes commonly used for this purpose have not been easy to keep sanitary; some of them do not have metal linings '10 and those that do have a metal lining are constructed so that the lining is fastened permanently to the inner walls of the case. The bottles heretofore were ordinarily kept from bumping together by the use of permanently fixed or loose wooden partitions.

Our certified milk case is designed to overcome these objectionable features and to provide a water-tight loose and removable inner metal liner or filler which can be taken out and cleaned and which can be easily replaced if it gives out before the outer case is worn out.

A further feature of the invention resides in the 1 metal rack which can be kept clean and sanitary and is more durable than wooden spacers as used in the old type of certified milk boxes. The removable filler may be provided with a slidable and foldable handle which can be folded down out of the way against the dividing wires of the filler or can be drawn up into operative position so that the filler can be used as a carrier when it is desired. The filler is constructed with peculiar type rivet-like stay rods which extend from side to side of the filler and which are formed with shoulders on the ends adapted to close the opening in the side wall through which the rivet rods extend to form a water-tight joint. This provides an economical structure of manufacture in that these rods form the spacers or partitions for dividing the filler into compartments for the botties.

The removable rack or filler of my case provides a milk case which is particularly adapted for use for certified milk and gives a construction where the case can be converted from a twelve quart to a twenty pint, or a thirty or sixty half-pint, merely by changing the racks in the case. This interchangeable feature of the racks Or fillers in the case is important, as the same size outer case may be converted into these different sizes readily by changing the filler within the same. The metal rack may be of a riveted structure with or without a bottom portion, or it may be made by welding the parts together to provide the water tight filler portion with the partitions in the same to divide the filler for receiving the different size bottles as defined.

It is also a feature to provide a holder or filler for the bottles in the certified milk case or carrier in which only two bottles may be contained 5 and where the stay bolts divide the filler into separate compartments for each bottle. This smaller filler constitutes the same structure in the removable filler or liner for the certified milk case. i 10 The invention includes a rivet stay rod of a pe culiar nature, wherein shoulders are provided on the ends of the rod adjacent a frustro-conical formed end which projects beyond the shoulders. This rivet stay rod provides the spacer 1 between the sides of the fillers and acts to form an effective means of providing a water-tight joint between the rod and the metal side wall when the stay rivet rod is anchored in place by upsetting the outer end of the frustro-conical 2'0 portion. In other words, when the ends of the stay rod rivet are riveted to the side walls, a tight joint is provided. This is an important structure because it prevents moisture from getting in around the riveted end of the rod and. rusting out the side wall so that the rods in a short time would become loose. In crate structure for mill: bottles and the like, it is believed this is a new development.

These features, together with other details 30 and objects of the invention will be more fully and clearly set forth in the specification and claim.

Figure 4 is a perspective view, looking up from the bottom of the removable filler for certified cases with a closed bottom.

Figure 5 illustrates a small certified milk case for two bottles of milk. 50

Figure 6 illustrates the removable filler for the certified milk case illustrated in Figure 5.

Figure 7 illustrates a sectional detail of the riveting or stay bolts or rods used in our removable fillers. 55

Figure 8 is a perspective view, a part of which is in section and part broken away, of one of the stay'rods used in making our removable filler for certified milk cases.

The drawings illustrate'our certified milk case A the outer casing portion of which is made of ,wood for the advantage of insulating and protecting' the contents of the oase. The case A is provided with a cover H which may be formed with an inwardly projecting portion It. This portion I0 may be covered with sheet metal if able filler like B so that the case may be con- I verted from a twelve quart to a twenty pint, or thirty or sixty half-pint, merely by changing the fillers B. In other words, the spacerrods I i are it is desired, to protect the same.

The certified milk case A is adaptedtojreceive the removable filler B which is made. with sheet metal sides I I and may be formed with a bottom portion I2 like the filler B, illustrated in Figure 4.

The filler illustrated in Figure 3 is formed without a bottom portion I2 and in this con I struction parallelly extending rivet stay rodsC.

are positioned close enough to each other and extended along the bottom of the filler B as illustrated in Figure .3 to iorma bottom engagement or rest for milk bottles such as D. The filler B is provided with other stay rods C which are also indicated as the stay rods I4 to distinguish them 7 from the stay rods (3 which form the rests for the r the same plane; then there is another set of these same rods extendingat right angles to these first rods I4, that also extend a horizontal'plane,

and these last rods are directly under the first rods and contact at their points of intersection so that the rods I l extending at right angles to each other between thesides II of the filler B form individual bottle compartments or spaces, such as E, to receive the bottles in the filler B and hold them spaced 'apart' from each other and to provide openings between the bottles so that ice may be packed in around the same.

It is desirable to'have two or more sets of par titioning rods such as M, each set extending at right angles to each other like as illustrated in Figure 3, and one set being placed in a' horizontal plane above the other set.

The spacer rivet rods C are of the construction illustrated in Figures 7 and 8, the body of the rod l5 may be round or fiat or any suitable formation, while each end is formed with a'shoul der l6 and projecting from the shoulder a frustro-conical riveted portion 51 is provided which may be riveted over to form the rivet head I8, like in Figure '7. The taperedend I1 provides a wedge shape which is tightened in the hole [9 when the head I8 is rivetedover and the shoulder I6 helps to lock the end of the rod '0 with a water-tight jQintpQnnected; to the from the ice leak out of the filler where a filler like B is used in the case A.

When a filler like B without a closed bottom as is illustrated in Figure 3 is used in the case A, then the case A itself metal-lined and the filler B is used therein. 7

It is also desirable to use a filler B in an ordinary case which .is not metal-lined and whe're no ice is used so as to provide difierent forms of fillers B for the different cases like .A. For instance, it is very desirable to have'the removpositioned difierently in the different removable fillers B to give more or less compartments such as E for the bottles, and where smaller bottles are held in the case A, one filler B may he of a lower height and one placed on top of the other, In this sense, the removable filler B is of extreme importance in providing a flexible case for milk bottles.

' The corners 2B of the fillers B are angularly disposed in relation to the walls ii so as to provide a space in the crate case A which permits a reinforcing member 2i to' be used in the inside of the case A at the corner, while the cut-01f corner or angularly disposed portion 2!! of the fillers B extend across in front of these reinforcing corners 2| and leave a space for the corner member'within the case. These fillers Bare formed, with a diagonal corner portion 29 which permits the filler B to slide into the case easily.

The fillers B maybe provided-with a sliding ioldable handle F which-is, formed with the loops 22 so that the handle can be folded down against the upper stay rivet M or lifted up as illustrated in dotted outline in Figure ,2, to carry or lift the -filler B. There are times when a handle of this nature practical for certified milk cases where it"is desired to carry the contents of the'filler B as a tray, particularly in lifting the bottlesout of the collection plate.

It is .also desirable to form the filler for the 5 case A as illustrated in Figure 6, in the form of a box-like tray member, having a' deep construction adapted to receive the bottles D and where a cou- 7 ple of stay rivets C are used to divide the filler may be provided Withahasp andeye G so that it is desired. ,7 I I Heretofore, cases for certified milk have been built withpermanent spacers or dividers in the same of wood or other material, but they have not been formed with a removable and interchangeable filler such as E which may be made divided into more or less compartments for the desired number of milk bottles to fit into the case A. The outer cases A may be made of a standard nature so that with the tray which is removable, such as B, the cases A may be converted into holders for quart or pint bottles or half-pints, yet maintaining the same size case A andwithout any loss of time the trays or fillers B maybe changed.

' The important feature of removable'fillers B resides in the structure with the stay rivets "C a lock can be placed upon the certified case A, if

which form joints between the rivets and the sides 75 or case of the tray or filler B and the interchangeable nature or removable feature of the filler itself. Owing to the fact that the trays or fillers B must be provided with divisions to receive the bottles in the individual compartments E and for the reason that it is necessary to have these trays or fillers sanitary so that they can be thoroughly cleansed to permit for the proper care in handling certified milk, it is important that they are removable and that they be of .a strong, durable nature so that they will withstand the handling and also protect the bottles when they are in place in the case A. The form and construction of the filler B is also important in accomplishing the desired results in conjunction with the case A. The fillers B may be used with suitable cases without the cover portion where it is desired to provide interchangeable inner trays or spacers to provide for the individual spaces for the bottles.

In accordance with the patent statutes, we have described and set forth the principles of our invention, however, we desire to have it understood that the description and drawings are only suggestive and that the invention should be considered within the scope of the following claim.

We claim:

In combination with a rectangular outer casing formed of wood having a cover portion adapted to be closed over said casing, a removable bottle display tray positioned in said casing, diagonally disposed corner portions formed in said tray to provide spaces at the corners in said casing, and .a series of rivet rods extending between the sides of said tray to provide spacers for dividing said tray into individual bottle compartments, said rods extending at right angles to each other and disposed in sets of horizontal planes, said rods virtually touching each other at their point of intersection, and rivet ends formed on said rods to unite the ends of said rods with a water-tight joint with said side wall.
